APPARATUS FORFUSING METALS.

Specification of Letters Patent.

Patented June 18, 1907 Application filed July 9,1906. Serial No. 325,362.

fected by an electrode which hassimultaneously also served as a means of supplying gas, while according to the present invent1on the gas supply is effected quite independently of the supply of currents. In this way the important result is first of all obtained, that the oxy en cannot act on the electrode which has liecome heated by the electric current, and cause it to become overheated, and secondlythe oxy en does not exercise a blowing action on t e electric arc.' For the latter purpose a partition may be in"' serted between the nozzles which serve for supplying gas and'the electrode which serves for su plying electricity, in such a way that the b ast does not blow on the arc, and on the other hand the electrode is protected from the overheating action of the oxygen from the nozzle.

More articularly the present invention conslsts 1n means for fusing or melting holes through sheets of metal, and in order that the details of construction and action of the lnvention .may be more clearly understood reference is made to the accompanying drawng in which one form of apparatus is shown 1n elevation partly in section.

a is a metal sheet which is to be melted through; I) is the nozzle to which ox gen is supplied in suitable manner through t e tube 0; several nozzles may also be employed and a mixture of oxygen and other gases may be supplied instead of oxygen.

(1 is an electrode'which is in connection with an electric conductor e. The latter is joined with one pole of a dynamo, accumula tor, or other source of electricity, while the piece of work a'is connected with the other pole in a suitable manner.

f is a sheet ofasbestos or like fire-proof material. Of course the parts I), d and f may be joined with one anotherin suitable manner. They may be arranged fixed, while the iece of work under the same may be moved. I ut a may also be fixed, while I), d, f are oined with oneanother making a separate tool with which it is only necessary to brush over the piece of metal in order to melt ahole through the latter.

In the drawing the whole device is shown as a single tool, having a rounded handle, which carries the gas nozzle, the partition and the electrode. The latter is held by a set screw in a holder, which in turn is held by a rod passin through the handle.

What I 0 arm as my invention and desire to secure by Letters Patent is:

1. A device for fusing metal comprising in combination'means connecting said meta to one pole of a source of electricity, an electrode, means connecting said electrode to the other pole of said source. of electricity, whereby an art may be formed between said electrode and said metal, and means insulated electrically from said electrode adapted to supply gas supporting combustion to said arc, substantially as described.

2. A device for fusing metal comprising in combination, meansconnecting said metal to one pole of a source of electricity, an electr -e, means connecting said electrode to the other pole of said source of electricity, whereby an arc may be formed between said electrode and said metal, and a nozzle insulated electrically from said electrode adapted to supply gas supporting combustion to said arc, substantially as described.

3. A device for fusing metal comprising in combination means connecting said metal to one pole of a source of electrlcity, an electrode, means connecting said electrode to the other pole of said source of electricity, whereby an arc may be formed between said electrode and said metal, a nozzle insulated electrically from said electrode adapted to supplygassupporting combustion to said are, and a partition between said nozzle and said electrode, substantially as described.

4. A device for fusing metals comprisin in combination means connectingsaid meta to one pole of a source ofelectricity, an electrode, means connecting said electrode to the other 'pole of sald source of electricity,

whereby an arc may be formed between said i electrode and said metal, a nozzle insulated In testimony, that I claim the foregoing as electrically from said electrode adapted to my invention, I have signed my name in 10 supply gas supporting combustion to said are, presence of two witnesses, this twenty-seva partition between said nozzle and said elecenth day of June 1906. v
